Please try updating that AMD video driver:

Good luck!  

Your COU is a tad under the minimum requirements, I'm starting to see a few cases like this today - both Intel and AMD.
UserBenchmark: Intel Celeron G3930 vs Core i3-2120 I suspect the 1.1.x patches are fussier about meeting the minimums. If you revert to the 1.03 game patch in the Steam Betas tab for the game, does that run okay?  

We now think this is an issue with dual CPU systems.

CPU or GPU slightly below the minimum requirements should not cause a crash like this. If that is confirmed there will be a hotfix soon to address that problem.

Sorry about that!

In the meantime you can revert the game to version 1.03 in the Steam Betas tab for the game, which does not have that problem.

There is not, I am sorry - MS do not provide any facility for us to enable that.
